n as shown at g. 2. l And it -is'held in place by means of vbolts orscrews, put through the holes P P, 85e.

A rib, F, is rigi ly fastened to the top of the damper,

rlhe damper, shown in the drawings, is 4so constructed as to leave asmall opening for gas and smoke to escape when it is closed, but otherforms, other thanthat shown, may be used, as the necessity of anyparticular case may require.

Operation.

The iianges B and D should be 'placed inside of the joints of the pipe,and the plate A turned round to a convenient point for reaching. the lugE, and the de Vice is then ready for use.

I claim that -this damper can be put in position for use much morereadily than those which have rods passing'throughv the pipe, and thatit is always free from soot and ashes, for, when it is opened, any sub-Stance Which may have adhered to it is removed.

Having thus described my' invention,

What I claim, and desire to secure by Letters Patent, isv The two-partcase, formed by the parts .A and M, having flanges D B for supportingthe joints of pipe, and a recess inside, in which a` damper, H, is madeto operate for regulating the draught, substantially as and for thepurpose set forth.

a part of this specification, in which-i Figure l is a perspectiverepresentation of -my invention. I

Figure 2, an inverted view of the upper plate, also showing the slidingdamper.

v Figure 3, a View of the inside of the bottom plate. l The nature ofthe present invention consists in the use of a two-part case, havingilanges forsuppoiting the joints of pipe, and a recess, in which asliding mper is made to operate, and close or open the draught.

To enable others skilled in theart to make and use my invention, I havemarked corresponding parts with Similar letters, and will novv give adetailed description.

A represents a cast-metal plate, having a circular flange, B, projectingupward, and used for supporting the lower' end of the top joint of pipe,and it has a slot, L, made through it, in which a lug, E, is arranged toslide, said lug being rigidly attached to the damper H, and used to openand close it.

The damper is made either of'.cast or wrought metal, and it isconstructed to run in a recess, I, which is made -in the under side ofthe' plate A, as clearly shown at iig. 2. And this recess is deep enoughto receive a plate, M, fig. 3, which plate has a flange, D, fig. l, forsupporting the lower joint of pipe, 4and it is made to Iit in a rabbet,J, in the flange of the recess,
